Studies on the ultraviolet difference spectra of proteins and polypeptides.
Changes in the ultraviolet absorption spectra of proteins associated with dcnaturation or proteolysis have been intensively investigated in recent years. These studies have been, in the main, restricted to the difference spectra of proteins and model compounds in the region between 270 and 300 rnp. The changes in this region have been assigned almost entirely to the alterations in the environme...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
The absorption spectra of benzene derivatives in the vacuum ultraviolet.
New photographs of the far ultra-violet spectrum of benzene are presented. The absorption from 2000 to 1800A (Amlx, c. 1980A) is regarded not as a part of the much stronger absorp tion of peak at 1790 A but as due to a separate transition. Sharp bands lying at 1790 A represent the first member of a previously reported Rydberg series. The spectra of toluene, xylene, monochloroando-dichlorobenze...
متن کاملNew Thiazoline-Tetralin Derivatives and Biological Activity Evaluation.
In this study, novel N'-(3-cyclohexyl/phenyl-4-(substituted phenyl)thiazole-2(3H)-ylidene)-2-[(5,6,7,8-tetrahydronaphthalen-2-yl)oxy]acetohydrazide (4a-4k) derivatives were synthesized and their anticancer potency were evaluated on human breast adenocarcinoma cell line (MCF-7), human lung carcinoma cell line (A549) and mouse embryoblast cell line (NIH/3T3) using the MTT method, DNA synthesis in...
متن کاملEffect of Substituents on Ultraviolet Absorption Spectra of Derivatives of o-Hydroxybenzophenone
Derivatives of o-hydroxybenzophenone are known as efficient photostabilizers. High absorption efficiency in the near ultraviolet region is a fundamental prerequisite for this application. Absorption spectra of derivatives of o-hydroxybenzophenone were measured by several authors [1—3]. Recently W. L. D i l l i n g [4] investigated the influence of solvents on the shift of absorption bands in be...
